摘要:
The present invention relates to a propulsion and braking system using a clutch, the system comprising: a device that has, embedded therein, a clutch operation pressure-regulating valve, and a clutch and gears for controlling a driven body in the same and opposite rotational direction of a driving body; and a control unit for regulating the rotational speed of the driven body so as to enable a continuous operation at a speed that is lower than a rated rotational speed by using the slip of the clutch, and controlling so that the engagement timing control of the clutch and engagement of same are sustained if the driven body requires operation at the rated rotational speed or higher, wherein, when a braking signal is inputted into the control unit during propulsion of the driven body, the control unit removes the operation pressure of the clutch embedded in the device that is in operation, activates the clutch for controlling the rotational direction of the driven body to the reverse rotational direction, and then regulates the operation pressure of the clutch by means of the valve so as to enable the control of the braking of the propulsive body. The propulsion and braking system using a clutch, according to the present invention, is related to all equipment requiring propulsion and braking.
摘要:
The present invention relates to a method and apparatus for detecting a misfire which may occur during the operation of an internal combustion engine, and which, in particular, not only detects a misfire, but also detects which cylinder of a multi-cylinder engine has misfired. The method and apparatus for detecting a misfire of an internal combustion engine according to the present invention involves detecting whether or not a misfire has occurred by means of the frequency which varies according to the rotational angular velocity of the rotating shaft of an engine, and quickly detecting which cylinder has misfired by matching the top dead center of a reference cylinder against the top dead centers of the individual cylinders, and using the peak position of the rotational angular velocity signal filtered by a band-pass filter. Therefore, by quickly detecting a misfire in an internal combustion engine and in which cylinder the misfire occurred, and taking preventative measures, an accident such as the stalling of the internal combustion engine can be prevented, and the service life thereof can be lengthened.
